This invention relatesto means designed for derailing tubs, trucks, and other railway vehicles, or diverting them off' apermanent way or track, in the eventxot their running away down or along the track, or attaining an excessive or uncontrollable speed; and the present application is a'division of application Serial No. 348,581, filed vMarch 20,

railway tracks of any description, for-de-i railing, diverting, or throwing oii'the track,

tubs, trucks, or other railway vehicles or the like, whether loaded or empty, which have acquired a predetermined excessive or uncontrollablespeed on the permanent way or track. a

The means according to this invention oonsitutes a simple and efficient "device for the purpose specified which, when the vehicles are running at or below the normal or a predetermined maximum speed, will allow them to remain on the track, and will operate, only on such speed being exceeded, to derail the vehicle.

According to this invention the derailing device consists of adefinite setting in or shaping of the track, so as to impart to a portion or portions thereof a transverse or lateral kink or bend, with an upward grade or incline (relative to the level of therails of the track) for aportion of the set or bend, in the direction of the travel of the vehicle alongthe permanent way.

The transverse set, or lateral kink or bend, may be provided by parts or castings placed between the adjacent ends of adjacent rails of the track, and shaped to provide the set or bend and the upward grade or incline; or

i the set or bend may be formed in the railsof the track themselves and the upward grade or incline be provided by pieces or castings shaped to correspond to the kink or bend in the rails and fixed on the top thereof at the set or bend.

The transverse set, or lateral kink or bend, causes the vehicle to be deflected or diverted laterally from the normal direction of travel and to be returned to said normal direction when the vehicle is running at normal or safe The invention is applicable for use onspeeds. The set or bend, combined the j i upwardgrade or incline,.cau'ses the vehicle to be derailed when it acquires an excessive or uncontrollable speed; whereas, at normal or. sate speeds, the vehicle passes over the device without being derailed.- ltjwill be undere stood fromtheforegoingthatthe eonstructionof the device is such that the upper surface. of the defiectin'gdevice rises above the normal plane of the rails of thetrack from both ends of the device. 7 i V The invention will be more fully explained withtheaid of the accompanying drawings,

wherein I illustrate two'forms thereof- In the drawings, I

Figs. 1 and 2 are plan viewandside eleva tion, respectively, of a portion of the permanent way or track, showing'one form of the invention, and

, Figs. 3 andA are similar views illustrating the other form of the invention. 7

Inthe form ofthe invention depicted in Figs. 1 and 2, the. transverseset, or lateral bend or kink, is formed in castings or parts made separate from the rails of the track and interposed between the adjacent ends of adj acent rails 1, 1 and 2, 2 of the track. Although the traek is shown as -Va horizontal track, it is to be understood that it may be either upwardly or downwardly inclined and the device still operate to derail the vehicle under the conditions hereinbefore' mentioned. Thecastingsforparts are so arranged relative to each other in the track thatthe sets or bends therein ar symm ric an i cline laterally in'the direction of the same ,8 indie-ates the, highest-points of the upwardly inclined portions ,9 of the de- -i their ends to'their" respective rails 1,"l ,-and"- 2, 2, by means of the fish plates 13.

of. ti is embodiment of the invention, the set or;s haping of the castings, orpartsis such that, in the event of a vehicle passing on to the derailing device at an BXCGSSIVG speed,

it is -'diverted ordeflected transversely, and

upwardly relative :to theiplane of the track,

by theportions 9, and, due its momentum, tends to continue in the samedirection, as indicatedby the dotted lines a. =zThe action of gravity compels the wheels rof'the vehicle to travel or movein a curved-path ortrajectory, as indicated the dottedcurvehih Fig.2. Thiscauses the wheels to leaveor jump clear of the track, thereby resulting in thederailment of the vehicle. v .1

In the other form. of the" invention shown" inFigs. 3 anclslythe rails l, 2, of the-track are constructed with a transverse set, .or'lateral bend, in the plane of the track, and appropriately shaped pieces or. members 14, providing the inclined surfaces Q'and 11, and constructed withthe set or bend corresponding to the set or bend in the rails, are fixed, by means ofscrews 15, on the tops of the rails l, 2. This constructionoperates toderail the vehicle in the. manner previously described in connection with Figsrl and 2.

In both of the forms of the invention showniin the drawings the device 'is sup ported by sleepers, but it will be apparent that it may be otherwise supported, asfor example by arranging it upon a metal plate or plates, or'on a cast base; or it maybe. cast or otherwise constructed integral with a base or base portionr I p It follows" from the foregoing description that the device inboth forms as described and illustrated, is entirely self-contained, and that there are no moving parts'liableto get out-of order, as in existing arrangements'em- 'ployed for the purpose Further, tha t my improved device is not, like the existingarrangeinents, difiicu'lt to install. It does not call for special attention, and'does not require the amount of space which is necessary for the working parts of existing devices. My device, being of'simple construction, is inexpensive to-produce and cannot get out of order. It is light in weight and inexpensive to install.

' WVhat I' claim as 'my invention and to protect by Letters Patent is l. A railway permanentway or track, a portion of which is constructedwith a, transdesire or track and are fixed to the vehicles are derailed when they acquire f an excessive or uncontrollable speed, said set or bend and incline being provided in parts which form portion of the permanent way the rails thereof, as set forth. p
